Arduino for STM32

Some more of my experiments: 1.I'm flashing it through ST-LINK 2.I select "USB CDC Serial" the test program void loop() { digitalWrite(LED_BUILTIN, HIGH); delay(1000); digitalWrite(LED_BUILTIN, LOW); delay(1000); } Variant №1 I do not make any changes or additions, ...

... but this is for stm32f401 not f411 this one has virtual comm port, you can try using putty to connect https://www.putty.org/ i think arduino ide serial monitor works as well edit: I uploaded a new bin file, should be the same but if it works the statistics for this is more accurate, previous ...

... { return; // <- return on entry, so no clock setting is done .... } this will run on HSI (internal oscillator) 16 Mhz (no usb), select uart for serial so that it won't hang on the usb. but the led should still light up if void setup() { pintMode(PC13, OUTPUT); } is run. the stm32cube programmer ...

I have tested this on 3 boards.
I think that the microcontroller freezes, because after the firmware, the COM port does not appear in the computer devices, although I turn on the "USB CDC Serial" setting

... during download operation: 00:00:00.493 RUNNING Program ... Address: : 0x8000000 Start operation achieved successfully 3. I select "USB CDC Serial", but after flashing the program into the microcontroller, the COM port is not displayed on PC devices (I checked in Windows Device Manager)- ...

... dividers are after all correct. usually, based on the values from the python script, usb would be working correctly i.e. at 48 mhz. select USB CDC Serial as your serial port and if you have codes like void setup() { Serial.begin(); while(!Serial); } void loop() { // echo usb serial input back to ...

... jumper/dupont wires. hold boot0 and release reset release boot0 1-2 secs later PA9 is the uart1 pin, putting it in input_pullup can cause the serial uart boot loader to take precedence over usb-dfu

... method connected via a USB cable and I can make the LED blink by specifying the PB2 pin. I can upload sketches repeatedly with no difficulty. The serial monitor works fine. So all's good, no? So, am I missing anything by having used the _pc13.bin file that I used? What is the purpose of having ...

... PB13, SD_CS_PIN); // #define SD2_CONFIG SdSpiConfig(SD_CS_PIN, DEDICATED_SPI, SPI_FULL_SPEED, &mySPI2) SdFat SD; File myFile; void setup() { Serial.begin(9600); Serial.print("Initializing SD card..."); if (!SD.begin(SD1_CONFIG)) { Serial.println("initialization failed!"); ...
